MetCirc
Bioc currentNavigating mass spectral similarity in high-resolution MS/MS metabolomics data metabolomics data
Release Lineage
Entered 3.4 · Oct 18, 2016
Current · Requires R 4.6
Description
MetCirc comprises a workflow to interactively explore high-resolution MS/MS metabolomics data. MetCirc uses the Spectra object infrastructure defined in the package Spectra that stores MS/MS spectra. MetCirc offers functionality to calculate similarity between precursors based on the normalised dot product, neutral losses or user-defined functions and visualise similarities in a circular layout. Within the interactive framework the user can annotate MS/MS features based on their similarity to (known) related MS/MS features.
